computer host in an IP network. Example: 192.168.2.1. It consists
of 2 portions: the IP network address, and the host identifier.
The IP address is a 32-bit binary pattern, which can be represented
as four cascaded decimal numbers separated by “.”:
aaa.aaa.aaa.aaa, where each “aaa” can be anything from 000 to
255, or as four cascaded binary numbers separated by “.”:
bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b” can
either be 0 or 1.
A network mask is also a 32-bit binary pattern, and consists of
consecutive leading 1’s followed by consecutive trailing 0’s, such
as 11111111.11111111.11111111.00000000. Therefore,
sometimes a network mask can also be described simply as “x”
number of leading 1’s.
When both are represented side by side in their binary forms, all
bits in the IP address that correspond to 1’s in the network mask
become part of the IP network address, and the remaining bits
correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.1001
0000.00000111, and if its network mask
is 11111111.11111111.11110000.00000000, it means the device’s
network address is
11011001.10110000.1001
0000.00000000 and its host ID is
00000000.00000000.00000000.00000111
. This is a convenient
and efficient method for routers to route IP packets to their
destination.
ISP Gateway Address: (see ISP for definition). The ISP Gateway
Address is an IP address for the Internet router located at the ISP's
office.
ISP: Internet Service Provider. An ISP is a business that provides
connectivity to the Internet for individuals and other businesses or
organizations.
LAN: Local Area Network. A LAN is a group of computers and
devices connected together in a relatively small area (such as a
house or an office). Your home network is considered a LAN.
